Unformatted text preview: Define = density of air 1.1 kg/m 3 h bin = number of hours/yr in bin V bin as bin avg wind speed [m/s] A = swept area of wind turbine [m 3 ] Then energy in bin E bin equals [watt-hr/yr]: Empirical E bin : download table of hours from web Theoretical E bin : use Weibull CDF. See Lec.18 Let x lo & x hi = lower and upper windspeeds for bin, resp.; x avg = average of x lo & x hi Then >>> simplify and solve...
